Structures, textures and classification of the Devonianmetavolcanics - Southern part of the Vrbno Group (Silesicum,Jeseniky Mts.)

There are described main volcanic rocks in the southern part of the Devonian Vrbno Group: basalts to trachyandesites with pillow structure, agglomerate metatufs of slightly alkaline trachybasalts to trachyandesites and sub-alkaline dacites to rhyolite, metamorphosed ignimbrites (chemically dacites, rhyolites and/or comendites-pantelerites, metadolerites (mostly subalkaline basalts) and acid metamorphosed subvolcanics.
